China Valve Packing Co., Ltd.

China Topper Valve Packing Seal Kits Co., Ltd. is a specialized manufacturer committed to delivering high-performance industrial valves, sealing gaskets, and packing solutions for the most demanding applications. Our product lineup—featuring gate, globe, and ball valves—is engineered to meet stringent API standards and integrates advanced low-emission graphite packing, ensuring exceptional performance under extreme pressure and temperature conditions.

In addition to valves, we supply premium sealing gaskets and packing materials designed to resist chemical corrosion, thermal cycling, and mechanical wear. All of our products undergo rigorous third-party testing and are certified to globally recognized standards, including API 622, API 624, API 641, ISO 15848-1, and TA-LUFT, with certifications verified by TÜV SÜD and TÜV Rheinland.

With a strong focus on innovation, we were among the earliest in the industry to invest in R&D for low-emission graphite packing systems to meet the strict regulatory demands of markets such as the United States. Our ongoing partnerships with top universities and research institutions enable us to tackle complex challenges in valve sealing, friction reduction, and wear resistance. These efforts led to our first TÜV-witnessed API 622 certification and have since earned us a comprehensive portfolio of international approvals.

What truly sets us apart is our scientific, systems-based approach to valve engineering. While others focus solely on machining, we delve deeper—studying the behavior of non-metallic materials under stress, developing advanced sealing surface coatings, and analyzing long-term performance in real-world conditions. Our multidisciplinary team—spanning valve design, sealing systems, materials science, and automation—works collaboratively to engineer smarter, more durable valves.

By bridging academic research with industrial application, we empower our customers to enhance operational safety, extend equipment life, and optimize efficiency. Our commitment to quality and innovation has earned the trust of clients across a wide range of industries.
